1 Project Summary

My task was to make a Linux Kernel Driver to program/debug Lattice MachXO2 FPGAs (used as routing fabrics) in AXIOM Beta Main Board. Two main goals of this project were:

  • To implement an ”upload“ interface to program MachXO2 FPGAs
  • To implement a debug interface for OpenOCD

I have yet successfully implemented an upload interface which enables us to upload a compressed bitstream (produced by Lattice Diamond tools) into MachXO2's SRAM. This allows a faster and easier way to upload new configurations while testing.

Google Summer of Code 2020 project.
